Movement due to soil and tree roots is inevitable. In footpaths without Lock Joint™, this movement causes vertical displacement between the pavers also known as ‘stepping’ and can cause tripping hazards. Lock Joint’s™ unique curve locks together the adjoining pathway paving sections, allowing for movement without any cracking or unevenness between pavement sections.

Our all-in-one expansion joint includes all the benefits of the Pinnable Lock Joint™ for easy installation, plus the addition of built-in compression foam, eliminating the need for sealants and bitumen board.

Lock Joint™ is our original, award-winning PVC control joint that can be installed in concrete paths and cycleways to reduce or eliminate cracking, sinking or displacement caused by tree roots and soil movement. It is an excellent solution for reducing maintenance costs and reducing hazards in any pathway.

Councils across Australia spend hundreds of thousands of dollars every year to maintain and repair our footpaths so they stay safe and hazard free. But, thanks to persistent tree roots and soil movement, those sites are likely to require future maintenance, sparking an expensive, relentless cycle of restoration.

The cost to install the preventative Lock Joint™ product is negligible compared to the amount saved in future repair costs.

Lock Joint Australia recommends spacings for Lock Joint™ joints to be a maximum of 1.5 times the width of a path.

For example, a path 2m wide should have spacings no more than 3m. However, where Lock Joint is being installed on sand, the spacings may be increased to a maximum of 2 times the width of the path. These recommendations may alter in different climate and soil conditions. In this case you should consult your engineer or Lock Joint Australia for further advice.

Joints such as saw cuts, or dummy joints, to create control joint are not necessary when Lock Joint is used in a path, as Lock Joint is a contraction/control joint.

Yes, Nata Certified engineers have independently tested Lock Joint™. Their results show that adjoining panels using Pinnable Lock Joint™ moved only 0.6mm when subjected to vertical displacement of 110mm

In similar tests, at a vertical displacement of 108mm, pathway joints using our competitors’ products caused sections to move in excess of 4mm. That’s a measurable 80% decrease in movement using Lock Joint.

Its patented sinusoidal (curved) design provides an even distribution of weight and locks together the adjoining pathway paving sections, allowing for movement without any cracking or unevenness between pavement sections. The included rubber capping seals the joint, preventing sand from entering whilst also prohibiting weed growth.

Lock Joint™ is the brainchild of a local concreter who noticed the constant maintenance required on footpaths, the unattractive look of traditional expansion joints and the slow and cumbersome process by which they were installed.

Yes. Our original Lock Joint™ and Pinnable Lock Joint™ designs are control joints, while our All-in-One Lock Joint shares the same design and includes a built in compression foam and is used as an expansion joint.
